Application
Apply Desert Brand Etch-Off Efflorescence Remover to either fresh (7 to 28 days old) or aged, bare concrete
or masonry surface using the following instructions. First, wet the surface thoroughly with water and let water
soak into pores. Then, liberally apply Desert Brand Etch-Off to the substrate using a Hudson Sprayer. Do not
apply in direct sunlight. Keep the surface moist for approximately 1/2 hour and then allow the product to dry
completely. This will allow the Desert Brand Etch-Off to completely react. The surface will turn completely
white as the Desert Brand Etch-Off dries.
To remove the Desert Brand Etch-Off, use a high pressure washer. If a high pressure washer is unavailable, wet
the area and rinse with a hose while scrubbing with a stiff nylon brush. Pressure wash or rinse the area
completely until the surface pH is 7 and the surface has a texture of 120 grit sandpaper. The surface may require
2 treatments until desired etching is achieved. Surface must be completely dry, wait at least 24 hours, and free
of dust before applying Desert Brand sealers or coatings.
For use on fiber cement products, apply liberally to the surface. Keep the surface wet and allow Desert
Brand Etch-Off to work for approximately 10 minutes. Rinse surface, oven dry and apply coating per
manufacturer instructions.

to 400 square feet of paver tiles. Coverage rates will depend on surface porosity.
